Tungsten carbide has been synthesized directly by ball-milling tungsten powder and activated carbon in vacuum. The structural development of the WC phase with milling times up to 310 h has been followed using X-ray, neutron diffraction and scanning electron microscopy. Subsequent annealing (at 1000 °C for 1 and 20 h) of material milled for 90 h or longer, results …

rial combining ball milling and subsequent hot pressing was reported to have improved the ZTmax up to 40% [17]. Motivated by this concept, we have applied higher energy ball milling on melted polycrystalline HMS and studied the effect on the phase constitution, microstructure and TE performance of the subsequently hot-pressed samples. 2 ...
